I haven't enabled the openDNS service but I am still getting some strange redirects to openDNS default pages when some URLs cannot be resolved.
This is after updating (reset to defaults and clear NVRAM) to the latest version of shibbys tomato build 104 AIO.

Even more strange is that it happens on some pages like an apache2 local network only host.
Example: on my LAN, one of the PC's runs an apache2 service with the url www.locapache2.com (the router is set up to resolve clients to this url over the LAN).

Sometimes I can get into it fine, but randomly, openDNS complains and sends me to a default url about it not being found and it's kind of like a web search page where it puts the failed url in a searchbox and offers suggestions…

This is strange because I don't have openDNS enabled, the only DNS service I have is freeDNS so that I can have remote access.

I do have the option Use dnscrypt-proxy checked on the Basic > Network page. Is that what could be causing the problem?
